Ghandi, who has also performed with Thievery Corporation, has revealed she got her period the night before the big race and chose to run with blood running down her thigh to raise awareness about women who have no access to feminine products.

In a post on her website, the Harvard Business School graduate writes, "I ran the whole marathon with my period blood running down my legs... for sisters who don't have access to tampons and sisters who, despite cramping and pain, hide it away and pretend like it doesn't exist.

"I ran to say, it does exist, and we overcome it every day."

Brave Ghandi finished the race in under five hours.
